LEARNING TO DO STALL TURNS
**NOTE** REMEMBER! THESE ILLUSTRATIONS ARE
TO GIVE YOU ONLY AN IDEA OF WHAT IS TO HAPPEN. YOU NEED TO BE MUCH HIGHER
IN ALTITUDE BEFORE TRYING ANY AEROBATICS FOR THE FIRST TIME. USE EXTREME
CAUTION AND HAVE AN INSTRUCTOR THERE WITH YOU AT ALL TIMES. ALSO THESE
ILLUSTRATIONS AND LEARNING TECHNIQUES ASSUMES THAT YOUR HELICOPTER IS
SET UP TO DO THESE AEROBATICS. MAKE SURE YOUR MIXES AND COLLECTIVE IS
SET CORRECTLY! GET AN EXPERIENCED FLYER TO CHECK THEM OUT AND DO FEW FIRST.
Photo Group #1
 
Photo group #1 shows the helicopter in straight and level flight flying
away from you. The read loop is the path you will want to take. Your first
stall turns will be more like a sloping turn or a sloppy turn with some
altitude increase. Just like doing a normal flat turn only with a little
more climb to it. You should do stall turns after the helicopter passes
you and on the "up wind" leg. You do loops and stall turns into
the wind so the helicopter will climb better and the wind will help maintain
lift.
Photo Group #2
 

Photo group #2 shows the helicopter just starting to pull nose up into
the stall turn. This is like the first part of doing a loop. You are still
"POWERING" into the loop or in this case, the "UP"
leg of the stall turn. The helicopter is still going into the stall turn
straight.
Photo Group #3
 

Photo group #3 shows the helicopter farther into the stall turn. Here
you are starting to turn right. In a "normal" stall turn you
would NOT be turning like you would in a "normal" turn, you
would not use any aileron or roll in your stall turn. Here you are adding
right roll. Since you are "pulling" back on the elevator, you
will get some turn out of it, just like an airplane..."Roll - n -
Pull". Basically it is a sloppy turn at this point. You are increasing
your altitude instead of a level turn. You are also pulling the throttle
back some to slow the process down some and so you don't climb too high.
The only reason you are slowing down the process here is because at this
stage you are learning stall turns. You want to gradually get into the
learning process so it doesn't cause any learning problems. Since you
know how to turn and fly around this should be "old" news to
you.
Photo group #4
 

Photo group #4 shows the helicopter at the top or peak of the turn. Its
just a follow through of step #3 but you will be pulling back on the throttle
more. In the final version of a stall turn you would be totally vertical
with the helicopter and at a 0degree pitch setting so the helicopter doesn't
blow in any direction. Don't worry about that right now.
Photo group #5
 

Photo group #5 the helicopter is now on the downward leg of the stall
turn. Here you still have right yaw and right roll. You will let the helicopter
fall a little as it comes through this point, but you are trying to have
the helicopter come out of the stall turn at the same level as it went
in so soon you will want to power back into forward flight like you do
as you come out of the loop. As you can see, its almost at that same position
that you would be in at the end of a loop. Its basically or almost the
same stick position as the the spot before the peak of the stall turn
and the peak of the stall turn.
Photo group #6
 

Photo group #6 shows the helicopter almost level again. you at the point
where your adding the power back in and leveling out. You are back into
the power and coming back forward on the elevator. You have taken most
of the right roll and right yaw out.
Photo group #7
 

Photo group#7 shows that you are back to a forward flight condition with
your throttle and elevator. You have finished with the right roll and
right yaw. If needed you will add a small amount of left roll to level
the helicopter.
After you have practiced this you will keep progressing with the stall
turn. With the "normal" style stall turn you will not use any
roll in it. You will climb to a vertical position, and take the throttle
/ collective pitch to 0degrees. At the peak of the stall turn you will
give right yaw for 180 degrees. Then you will travel back down the same
path as you went up. Ideally you will want the turn to be completed at
that split second the helicopter comes to a complete stop at the top of
the stall. Then you will exit at the same altitude you went in and fly
out. You should always do your stall turns "UP WIND" till you
get them down. The wind will give you increased altitude for the stall
turn.
